SET OF TOY INTEB'FI'JETING BUILDING BLOCKS.

Application a October as, 1823,"Serlal1lo.671,557, and in AustriaNovember 14, 1922.

This invention relates to sets of toy interfitt-ing building blockscomprising blocks or figures or groups of blocks or figures, such as forinstance houses, furniture, and the like, which are adapted to be set upsingly or separately, and the invention has for its object to provide animproved set wherein the box for containing these blocks or fi ures(hereinafter termed blocks) is itse f constituted by the assemblage of aplurality (consistin of a part of the totality of the set of bloc s)which when properly fitted together, will constitute a structure that isnot liable to fall to pieces readily.

For this object blocks or groups of, blocks made in one piece are unitedin pairs, and engaged with one another so that to form plates which thenconstitute the walls of the box for the reception of the residual 2blocks of the set, and have such dimensions that the internal capacityof the box is able to contain just the whole of the said residual blockswhen these have been suitably fitted together. Preferably the blocksdesigned to constitute the box are made of angle shape, whereby not onlthe ri idity or firmness of the stance d the individual blocks, but alsothe fitting together of thebox is facilitated.

An eifective rigidity of the assembled walls of the box is attained whentwo pairs of angle shaped wall-blocks are provided of which the pairwhich is united to form a rectangular frame encloses the other pair inthe transverse direction, and thus constitutes a completely closedchamber adapted to receive the other blocks.

A constructional form of an improved toy building block set accordin tothis invention is illustrated by way 0 example in the accompanyingdrawings in which:

Figure 1 is a perspective view of a box adapted to be formed by means'ofangle ieces designed to constitute roups of blocks assembled together,the ox being shown drawn apart in .both the vertical and horizontaldirections.

Figure 2 shows the angle pieces of the outer shell, the rear pair ofblocks being shown fitted together, whilst the upper block has beenremovedfrom the lower block of the front pair.

Figure 3 shows the box completely closed.

Figure 4 shows the box in a half finished state, at the back 'theouterpair of angle plates is shown upright and inside the same, the innerlower pair of angle'plates is shown horizontal; the other blocks whichare intended to fill the interior of the'box, are shown in course ofbuilding upon the said inner lower pair.

The illustrated example consists of a plurality of blocks representinghouses and rows of houses which are suitably ainted, or subdivided bylines not shown. 'Fhe zigzag abled roofs a of two rows of houses whicare united together to constitutea single plate portion A, are cut froma rectangular plate, preferabl of angle shape,

in such a manner that t e two parts with the roof surfaces fit exactl inone another. The joints may be pr uced by sawing throu h or cutting asingle late, or they may he roduced separately rom separate plates. hetwo pairs of angle plates constitute a rectangular frame. In order toclose the interior of the box on all sides, there is provided a secondpair of angle plates B which (like the plates A) are composed of pairsof mutually supplementing looks, but so dimensioned that the frameformed by B B is' adapted when fitted around the frame formed by A A toconstitute a cube-like body closed on all sides, (Fi 3). The residualblocks or groups of bloc s b 0 etc., are fitted into the interior of thebox which is partly opened (Fig. 4), and these blocks or groups ofblocks are so designed as regards numbers and shapes that when they aresuitably fitted together they will fill completely the interior of thebox. Since this operation requires certain amount of ractice, it willhave the character of a. cubical puzzle game.

In setting up the blocks the longitudinal groups of blocks 'thatconstitutes the box plates, serve for the construction of streets oropen spaces, whereas, the blocks contained in the interior of the boxare adapted to form short rows of houses or single buildings to beerected u on'the 0 n 5 aces bounded by them. p pe P The parts of the boxmaybe provided with tongues or fillets d, projections, etc., which musthowever not hinder the assemblage of the blocks to form the box.

In order to prevent the parts of the box from falling apart unobstrusivefastenings such as for instance ress-studs, fishnlates or the like (notshowng, may be provided.

What I claim is 1. A toy comprising a pair of angular members, each ofsaid members being pro-- vided with one irregular edge, said irregularedges being adapted to fully contact and interfitwhen brought together,and a second pair of angular members, each of which is provided with oneirregular edge, the irreg pair of members abut the ends of the legs ofthe second pair of members.

2. A toy as claimed in claim 1 including third andv fourth pairs of anular members arranged within the first an second pairs of members, eachof the members of said third and fourth pairs having an irregular edgeadapted to fully contact and interfitwith another of said members, saidthird and fourth pairs of members being further adapted to form arectangular frame, whereby the four pairs or members in assembledrelation constitute a closed hollow box.

In testimony whereof I have signed my name to this specification.
